Having intermittent issues with a Miprom Hydro for the last few years. Symptoms are in response to a hall call the doors may open half an inch, half way or not at all. Sometimes they open all the way and have no dwell time. Two stops, issue occurs at both landings. Issue also present with car calls. If you hold the button, hall or car, the doors will continue to open.
To no avail, the following items have been changed: all input cards, all output cards, both backplanes, power supply card, power supply, relay board, timer board, SRB, the board next to the SRB (can’t recall the name), door operator board, cable from operator to detector edge, limits in door operator, hoistway switches and traveling cable wires have been swapped around.
This issue may occur one in a week or remain failed for several days in a row.
I’ve finally got my hands on a tool and the car is currently failing.
Moving the run/debug jumper on the SRB yields no action in the debug menu.
Does anyone have any diagnostic information they can share?
